Slowing down as you run out of coins is a pretty interesting mechanic! I think I would have liked having a minimum speed, since it was pretty easy to get stuck - I ended up falling down a hole and couldn’t get out or collect any coins because my speed got too low. The super-fast jump also felt a little odd when paired with low speed from lack of coins.
The first time I almost made it home, the block ran out of speed right before I got there, haha - but once I knew where it was, it was easy to get there again. For replayability you could try having the house spawn in random locations to find every time, maybe?
I loved the juicy animations on the box - for just being a red square he really felt alive!
Fun little game, nice work!
